Abstract
Described herein is a method for operating an internal combustion engine (10). The internal combustion engine (10) includes at least one cylinder (11). The at least one cylinder (11) is connected to an exhaust pipe (12) having an air mass sensor (16), an exhaust pipe (13) having an λ-sensor (17), and an exhaust return line (14) having an exhaust return valve (15). The air mass sensor (16) serves to generate an air mass sensor signal (LMsens), the λ-sensor serves to generate a λ-sensor signal (λsens), and the exhaust return valve (15) is set by a setting signal (AGR). The method includes forming a target injection volume (Emsoll); forming the setting signal (AGR) of the exhaust return valve (15) in dependence on the air mass sensor signal (LMsens); and indicating whether the air mass sensor (16) is working correctly or is defective by means of a signal (HMdef). According to the present subject matter, the method further includes forming an air mass replacement signal (LMmod) for the air mass sensor signal (LMsens) in dependence on the λ-sensor signal (λsens) and the target injection volume (EMsoll); and in case of a defective air mass sensor signal (LMsens), forming the setting signal (AGR) in dependence on the air mass replacement signal (LMmod).
